Background. Propofol is a popular intravenous anesthetic and varieties of formulations were produced from different laboratories. The present study compared efficacy of propofol of different laboratories and different concentrations (1 and 2%) during induction of anesthesia.Methods. Seventy-five scheduled surgical patients were randomly allocated into three groups. The patients of group D1 received AstraZeneca Diprivan 1% (Osaka, Japan) at a rate of 40 mg kg−1 h−1. Group M1 was given 1% Maruishi (Maruishi Pharmaceutical, Osaka, Japan) and group M2 was given 2% formulation at the same rate of propofol. Achieving hypnosis was defined as failure to open their eyes in response to a verbal command and the venous blood sample was withdrawn.Results. The hypnotic doses of M2 were significantly larger (D1:91.4±30.9, M1:90.7±26.7, and M2:118.4±40.2 mg, resp. (mean ± SD).p<0.005). Age and gender were selected as statistically significant covariates using general linear model-ANOVA. The blood concentration showed no significant difference among the groups (3.73±2.34,4.10±3.04, and4.70±2.12 μg mL−1, resp.).Conclusion. The required dose of propofol was different among the formulations; however, the serum concentration showed no significant difference. This trial is registered with UMIN Clinical Trial Registry:UMIN000019925.

ABSTRACT Objective:  To assess lateral differences between ossification events and stages of bone development in the hands and wrists utilizing Fishman's skeletal maturation indicators (SMIs). Materials and Methods:  The skeletal ages of 125 subjects, aged 8 to 20 years, were determined with left and right hand-wrist radiographs using Fishman's SMI assessment. Each subject was also given the Edinburgh Handedness Questionnaire to assess handedness. The skeletal ages of both hand-wrist radiographs were analyzed against each other, handedness, chronologic age, and gender. Results:  There were no significant differences overall in right and left SMI scores (P  =  .70); 79% of all patients showed no difference in right and left SMI scores, regardless of handedness, gender, or age. However, when patients were categorized based on clinical levels of SMI score for the right hand-wrist, there was a significant difference (P  =  .01) between the SMI 1-3 group and the SMI 11 group. Subjects in the SMI 1-3 group were more likely to show a left &gt; right SMI score, while subjects in the SMI 11 group were likely to show a right &gt; left SMI score. Conclusion:  Although no significant overall lateral differences in SMI scores were noted, it may be advisable to obtain a left hand-wrist radiograph and/or additional diagnostic information to estimate completion of growth in young surgical patients.

Abstract Background: Postoperative cognitive dysfunction (POCD) is the decline in cognitive ability that occurs between one week and one year following surgery. POCD has been reported to occur in 5% to 26% of elderly surgical patients and its incidence varies with demographic, clinical, and surgical variables. Previous studies have shown that dexmedetomindine (DEX), a highly selective α2 adrenergic receptor agonist, has many effects that include opioid-sparing properties, decreased required anesthetic medication, and neuroprotection in animal models. Ultimately, DEX may benefit cognitive ability in the postoperative period. Therefore, we hypothesized that intraoperative infusion of DEX would reduce early POCD and interleukin-6 (IL-6) levels in elderly surgical patients compared to placebo. Methods: This randomized, double-blind, controlled trial enrolled 96 elderly patients that underwent video-assisted thoracoscopic lobectomy (VATL) between May 2017 and April 2018. The enrolled subjects were randomly assigned in a 1:1 ratio to receive intravenous dexmedetomidine (DEX Group) or placebo (0.9% normal saline, Saline Group) as a continuous infusion at a rate of 0.5μg/kg/hr starting at anesthesia induction until incision closure. All subjects received total intravenous anesthesia (TIVA) during surgery and patient controlled epidural analgesia (PCEA) following surgery. The primary outcomes were to determine the incidence of POCD and IL-6 expression at postoperative day (POD) 1, 2, and 7. The secondary outcomes were to evaluate the degree of pain on POD 1 and 2, as well as adverse events throughout the study. Results: 96 eligible subjects (48 per group) were randomized, dosed with study medication, and evaluated per protocol. There was a significant difference on POCD between the DEX and saline groups on POD 1 (6.3% vs. 20.8%, p-value <0.05) and POD 2 (4.2% vs. 16.7%, p-value <0.05). The IL-6 levels were significantly lower in the DEX group when compared with saline group during POD 1 and 2 (p-value <0.05). IL-6 returned to baseline levels on POD 7. There was no significant difference in POCD on POD7, and overall there were no significant differences in the incidence of adverse events between both groups.Conclusions: The administration of intraoperative DEX in elderly patients undergoing VATL decreased the incidence of early POCD. Clinical Trial Registry: This study was registered on Chinese Clinical Trial Registry with the ID ChiCTR-IPR-17010958.

Radiographic Mandibular Indices serve as easy and relatively cheap tools for evaluating bone mineralization. Objectives: To examine the effect of age and gender on three mandibular indices: the panoramic mandibular index (PMI), the mandibular ratio (MR) and the mandibular cortical index (MCI), among Libyan population. Methods: The three indices were measured on 317 digital (OPGs) of adult humans (155 males, 162 females). The sample was divided into six age groups (from 18-25 years through 56-65 years). The measurements were analyzed for interactions with age and sex, using SPSS (Statistical Package for Social Studies) software version no. 22. The tests employed were two way ANOVA, the unpaired T-test and chi-square test. Results: The mean PMI fluctuated between 0.37 s.d. 0.012 and 0.38 s.d. 0.012. among the sixth age groups. One-way ANOVA statistical test revealed no significant of age on PMI. On the other hand gender variation has effect on PMI, since independent sample t-test disclosed that the difference between the male and female PMI means statistically significant. ANOVA test showed that the means of MR among age groups showed a negative correlation i.e. MR mean declined from 3.01 in 18-25 age groups to 2.7 in 55-65 age groups. In contrary, the gender showed no effect on MR according two sample t-test at p> 0.05. In regards with MCI, statistical analysis showed that it affected by age that is C1 was decreasing by age while C2 and C3 were increased by age. Using chi square test the result indicated that there is a significant difference among the different age group and the two genders in MCI readings. Conclusion: PMI was influenced significantly by age but minimally by the gender. MR is not affected by gender but has a negative correlation with age. MCI is affected by both age and gender

Objective(s). The purpose of this study was to explore the effectiveness of wideband acoustic immittance (WAI) in the diagnosis of otosclerosis by comparing the differences in the energy reflectance (ER) of WAI between patients with otosclerosis and age- and gender-matched normal hearing controls in the Chinese population. Methods. Twenty surgically confirmed otosclerotic ears were included in the otosclerotic group. The ER of WAI at ambient and peak pressures, resonance frequency, and 226-Hz tympanogram were collected prior to surgery using a Titan hearing test platform (Interacoustics A/S, Middelfart, Denmark). All diagnoses of otosclerosis in the tested ear were confirmed by surgery after the measurements. Thirteen normal adults (26 ears) who were age- and gender-matched with the otosclerotic patients were included as the control group. Results. At peak pressure, the ERs of otosclerotic patients were higher than those of the control group for frequencies less than 4,000Hz and were lower for frequencies greater than 4,000Hz. In addition, within the analyzed frequencies, the differences observed at 2,520Hz was statistically significant (p<0.05/16=0.003, Bonferroni corrected). At ambient pressure, the differences observed at 1,260 and 6,350Hz were statistically significant (p<0.05/16=0.003, Bonferroni corrected). Although the differences between the otosclerotic and control groups exhibited similar trends to those in studies implemented in Caucasian populations, the norms in the present study in the control group were different from those in the Caucasian populations, suggesting racial differences in WAI test results. Regarding the middle ear resonance frequency, no significant difference was observed between the two groups (P>0.05). Conclusion. WAI can provide valuable information for the diagnosis of otosclerosis in the Chinese population. Norms and diagnostic criteria corresponding to the patient’s racial group are necessary to improve the efficiency of WAI in the diagnosis of otosclerosis.

Aims: Elevated serum lipid concentrations in childhood are thought to be risk factors for the development of cardiovascular disease later in life. The present study aims to provide age- and gender-related reference intervals for total cholesterol (TC), high-density lipoprotein (HDL) cholesterol, and non-HDL cholesterol in healthy school children. We also investigated the prevalence of dyslipidaemia using the published criteria for these biomarkers. Methods: Venous blood and anthropometric data were collected from 1340 children in the HOPP study, aged between 6 and 12 years. Age- and gender-related reference intervals (2.5th and 97.5th percentiles) were established according to the IFCC recommendations, using the software RefVal 4.10. Results: Gender differences were observed for total cholesterol and non-HDL cholesterol, but not for HDL cholesterol. Age differences were observed for total cholesterol. The reference intervals were in the range of 3.1–5.9 mmol/L for total cholesterol, 1.0–2.4 mmol/L for HDL cholesterol and 1.4–4.2 mmol/L for non-HDL cholesterol. Dyslipidaemia prevalence was as follows: increased TC 9.6%, decreased HDL 1.6%, and increased non-HDL 5.6%. Conclusions: Age- and gender-related reference intervals in a Norwegian population are similar to those reported in other countries. The prevalence of dyslipidaemia among Norwegian children is significant, emphasising the importance of appropriate reference intervals in clinical practice.

Abstract Objective To measure the level of hair Mg, as well as its level in serum, in patients with epilepsy and compare them to the levels found in non-epileptic age and gender matched children, and to explore any potential correlation between either serum or hair level of magnesium and seizure characteristics in children with idiopathic epilepsy. Methods An observational cross-sectional study including 50 children with idiopathic epilepsy and 100 non-epileptic age and gender matched control subjects. Cases were subjected to full history taking, examination and measurements of serum and hair levels of magnesium, control subjects only had their serum and hair level of magnesium measured as for the cases. Results The mean serum magnesium was 29.11 ± 13.42 ug/ml for cases and 27.67 ± 7.24 ug/ml for controls and the median hair level of magnesium was 42.22 ug/g with IQR of 25.9 - 56.82 for cases and 38.6 ug/g with IQR of 25.21 - 61.25 for controls. No statistically significant difference was observed between both groups as regards either serum or hair magnesium levels. No statistically significant correlation was observed between either hair or serum levels of magnesium and seizure characteristics though the correlations were nearing statistical significance for the hair magnesium content. Conclusion Hair magnesium level may be better correlated to seizure characteristics and control than serum levels in patients with epilepsy.

Background : Fibromyalgia syndrome (FMS) is defined as widespread and persistent pain in the musculoskeletal system. There are limited reports regarding the prevalence of fibromyalgia syndrome in patients with advanced kidney failure undergoing regular hemodialysis. Therefore, this study aimed to evaluate the prevalence of fibromyalgia syndrome and its risk factors in a large proportion of patients under the hemodialysis condition. Materials and Methods: In this cross-sectional study, 293 patients who were admitted to the hemodialysis ward were evaluated for fibromyalgia syndrome in an educational hospital. The questionnaire was designed according to symptom severity score (SS score) and widespread pain index (WPI) criteria. The correlation between FMS and various variables, including demographic, clinical, and biochemistry biomarkers, was also precisely calculated by logistic regression. Data were analyzed using SPSS v.17 statistics software. Results: The results showed that, of 293 hemodialysis patients, 130 patients (44.4%) had fibromyalgia, the mean age of patients with and without fibromyalgia was 61.09 ± 15.36 and 53.49 ± 15.38 years old, respectively (P = 0.001). Moreover, there was a significant difference in terms of gender among patients with fibromyalgia syndrome (P = 0.001). To note, there was no significant relationship between the kidney failure etiopathogenesis, duration of dialysis, body mass index (BMI), Kt/v index, history of peritoneal dialysis, and laboratory parameters with fibromyalgia in hemodialysis patients (P > 0.05). However, our findings revealed that both age and gender could be considered as the predictor variables associated with fibromyalgia in patients undergoing hemodialysis. Conclusion: Taken together, in this study, we found that age and gender would be the critical factors in terms of the fibromyalgia syndrome in patients undergoing hemodialysis.

<p>This study was conducted to compare with the executive function of ADHD versus normal male and female children. To obtain this objective, 30 ADHD children referring a private psychological center for the first time who had taken no medication for this disorder, and 30 normal children from one of the schools of District 14 in Tehran were selected randomly who were of the same age and gender of ADHD children. Wisconsin test was used as a measurement tool. Results showed that there is a significant difference between the average scores of the executive function of normal and ADHD children as well as average scores of the executive function of normal boys and ADHD children at the 0.01 level. In addition, there was a significant difference between the average scores of the executive function of normal girls and ADHD girls at the 0.05 level according to which null hypothesis is rejected. Therefore, ADHD children are of lower executive and cognitive function compared to normal children and have extensive cognitive deficits. Therefore, they require medications along with special training and rehabilitation.</p>

Background: The rib cage, such as the thoracic spine and ribs, influences glenohumeral mobility and the development of shoulder disorders. Objective: To evaluate movements of the ribs, thoracic vertebrae during bilateral arm elevation and to clarify the characteristic influences of age and gender. Methods: Subjects comprised 33 healthy individuals divided into a young group (10 males, 7 females; mean age, 25 years) and a middle-aged group (8 males, 8 females; mean age, 52 years). Chest CT was performed with two arm positions: arms hanging downwards; and arms elevated at 160°. Images were three-dimensionally reconstructed to evaluate rib movement, extension angle of thoracic vertebrae. Results: Maximal movement was observed at the fifth rib, and rib movement decreased with increasing distance from the fifth rib in both the groups. In males, movement of the second to fourth ribs was smaller in the middle-aged group than in the young group (p < 0.05). Movement of the first to ninth ribs was smaller in females than in males (p < 0.05). No significant difference in the extension angle of the thoracic vertebrae was found. Conclusion: Fifth rib movement is the largest among all ribs during bilateral arm elevation. Reduction of upper rib movement initially arises as an age-related degradation in males. Women exhibit less rib movement during bilateral arm elevation.

Colorectal cancer has became burden in the world.The latest study shows that colorectal cancer is the third most common cancer in men and second most common cancer in women globally. There are difference characteristic of epidemiology in every countries. Moreover, there is no study that represents epidemiology of colorectal cancer in Indonesia yet, especially in East Java. The aim of this study was to describe colorectal tumor profile by age and gender in Gastroentero-Hepatology Center, Dr Soetomo Hospital. This study has received a certificate of Ethical Clearance No.273/Panke.KKE/IV/2015, a descriptive retrospective study. We collected data using medical records, and patients who have been colonoscopy examination and suspected colorectal tumor were included. There were 201 patients, divided to 100 males and 101 females. The peak of incidence was on 51-60 years old group, but on the 31-40 years old incidence of colorectal tumor was increased. The youngest patient was 17 years old. And tumors are more likely develop in distal area, especially in rectum. This study shows a different characteristic profile of colorectal tumor, where tumor is developed at young people and there is no significant difference between male and female for the incidence.
